Chapter 3, Problem 3.131QP

Interpretation Introduction

Interpretation:

The maximum mass (kg) of Sodium azide that can be produced in the given reaction should be determined.

Concept introduction:

Mole:

Number of atoms present in gram atomic mass of element is known as Avogadro number.

Avogadro number is $6.022136\times {10}^{23}$

One mole equal of atom equal to Avogadro number $(6.022136\times {10}^{23})$ hence, 1 mole of Iron $\text{(55}\text{.9 g)}$ contain atom $6.022136\times {10}^{23}$ $\text{Fe}$ atoms.

The mole of taken gram mass of compound is given by ratio between taken mass of compound to molar mass of compound.

$\text{Mole}\text{=}\frac{\text{Mass}}{\text{Molar}\text{mass}}$

Limiting reagent:

The mole of the product formed in the reaction is determined by the mole of one of the reactant, this reactant is known as limiting reagent.

In the reaction, the limiting reagent is completely react to give a product. After completion of this reagent the reaction will stop.
